Errata for Volume 113

Abstract

WE HAVE been informed by the author (Kipnis, F.
Science, 113, 40 [1951] that in his Formula XVII,
page 42, he omitted - OH at position 5. In the same
article, column 1, page 42, the paragraph which begins, "The pseudosapogenins, dihydrosapogenins, etc.,"
became pied after leaving our hands. This should read:
"The pseudosapogenins, dihydrosapogenins and dihydropseudosapogenins, assuming that all have similar
ring structures, are named as pseudosapogenans."—
